SPECIFICATION forming part of Letters Patent No. 415,538, dated November 19, 1889.

Application filed November 22, 1888- Serial No. 291,575. (No model.)

To all whom it may concern,.-

Be it known that I, GODFREY H. LAsAR, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Type-IVriting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciication, and in which- Figure I is a detail sectional view showing part of a type-writer and illustrative of my invention. Fig. II is an enlarged perspective View of one of the brackets for securing the type-bars to their supporting segment or frame. Fig. III is a horizontal section taken through the pivot-holes of one of the brackets.

My invention relates to an improved method of attaching the bars of a type-writer to a supporting` frame or segment; and it consists in features of novelty hereinafter fully described, and pointed out in the claims.

` Referring to the drawings, 1 represents the base of a type-writer; 2, the operating-levers; 3, the frame or segment supporting the typebars; 4, one of the type-bars, and 5 the platen. 4

My present invent-ion relates entirely to the manner of securing the type-bars to the supporting frame or segment; and it consists in brackets 6, each of which is adapted to support two type-bars. Each bracket is preferably formed with a shoulder 7, that rests on the frame 3, as shown in Fig. I, and is held on the frame by a set-screw S. (See Figs. I and II.) The upper end or head of each bracket is formed with two vertical slots or openings 9, and two horizontal perforations 10. The slots or openings 9 receive two of the type-bars, and the perforations 10 receive the pivot-pins 11, (see Fig. II,) that connect the type-bars to the bracket and permit of the movement of the former in thevlatter as the machine is operated. The holes 10 are made from each side of the bracket, so that each is at right angles to the slot 9, through which it passes, as shown in Fig. III, so that the pins 11 when inserted will be exactly at right angles to the length of the typebars. Thus the typebars are made to operate or move accurately on their pivots.

There are advantages arising from the use of brackets supporting two type-bars over a slotted bracket orframe supporting a greater number of bars, and also over a bracket supporting but one type-bar. A few of these advantages will be mentioned.

First. It permits of a more ready adj ustment and fitting of the type-bars for this reason: The central wing between the slots 9 is of just the thickness to hold the type-bars the proper distance apart. Vhen the type-bars are put in place in the slots, the bracket may be placed in a vise to tighten the two outer wings upon the type-bars, so as to avoid any loose movement of the bars', and the two outer wingsbeing of much less thickness than the central wing all the springing will be done in them, and none of it takes place in the central wing. Thus the type-bars are made to tit snugly in the slots, though they maybe of slightly-different thicknesses, and at the same time are held just the proper distance apart to make them strike accurately the printing-center of the platen. This adjustment cannot be accomplished with abracket supporting a single type-bar; nor can it be accomplished with a segment or frame supporting a greater number than two of such type-bars.

Second. By making the brackets to support two type-bars they have more rigidity and Iirmness than a small bracket supporting but one type-bar, and at the same time have not the liability of containing blowholes, frequently found in a frame or segment supporting all of the type-bars.

Third. By forming the bracket to support two type-bars the journal-openings 10 can be formed so as to be at right angles to the openings 9, so that the pins 11 will be at right-angles tolthe type-bars, whereas, with a frame or segment supporting all or a greater nulnb'er than two of the type-bars this cannot be accurately accomplished, and at the same time there are only half the number of brackets required that would be necessary if there were a separate bracket for each type-bar.

I claim as my invention-i l. In a type-Writer, a supportingbraoket Slotted radially to receive two type-bars and perforated to receive the journal-pins of the bars, substantially as and for the purpose set 5 forth.

2. In a type-Writer, the combination of the supporting-frame 3, brackets 6, type-bars 4, and platen 5, each bracket; G havin g two radial slots 9 and t-Wo perforations l0, each slot receiving a type-bar, and' each perforation re- 1o Ceiving a j ournal-pin, Substantially as and for the purpose set forth.
